Restore Full Electrical Function to Your GM Truck or SUV
Are you battling frustrating electrical gremlins in your vehicle? Flickering lights, unresponsive power windows and locks, or a security system that acts on its own are classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your truck’s body electronics, and when it fails, it can cause a cascade of confusing and unpredictable problems. This replacement Body Control Module, compatible with service number 09371990, is the definitive solution to restore your vehicle’s systems to perfect working order.
We take the guesswork and hassle out of the repair. Unlike a generic module from a parts store or salvage yard, this BCM is professionally programmed to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This crucial step ensures that the module communicates flawlessly with your truck’s other computers, retaining all original features and preventing compatibility conflicts. Simply provide your VIN after purchase, and we’ll handle the complex programming, delivering a part that’s ready for a straightforward installation.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights that stay on, flicker, or won’t turn on at all.
- ✔ The security or anti-theft system preventing the vehicle from starting.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Dashboard warning lights illuminating without a clear cause.
- ✔ Wipers operating intermittently or at the wrong speed.
- ✔ Inaccurate gauge readings on the instrument cluster.
We had a 2000 Sierra come into the shop with a classic BCM failure story. The owner had already replaced the driver’s side window motor twice, convinced it was faulty because it would work one day and not the next. He was frustrated and out of pocket for parts and labor that didn’t fix the issue. A quick scan showed communication faults with the BCM. After installing a VIN-programmed module, not only did the window work perfectly, but the intermittent dome light and door lock issues he’d learned to live with also vanished. It’s a reminder that the BCM is the ‘brain’ behind these components, and diagnosing it first can save a lot of time and money.
Why Choose a VIN-Programmed 2000 Silverado 1500 BCM?
The Body Control Module in your GM vehicle is not a one-size-fits-all part. It’s coded with specific information about your truck’s options, from the type of transmission and security system to whether it has keyless entry. Our VIN programming service ensures this replacement module is a perfect digital clone of your original, but with the latest GM software updates. This eliminates the need for expensive trips to the dealership for programming, making it a cost-effective and efficient repair for both DIY mechanics and professional shops.
Installation and Post-Install Procedures
Installation is typically straightforward, with the BCM located under the driver’s side of the dashboard. While our programming makes this a near plug-and-play solution, some vehicles may require additional calibration steps, known as ‘relearn procedures,’ to sync all systems perfectly.
- Airbag System Sync: In some cases, the airbag warning light may illuminate after installation. This indicates a sync mismatch between the new BCM and the airbag system’s SDM (Sensing and Diagnostic Module). A professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
- Brake Pedal Position Relearn: To ensure accurate brake light operation and proper function of the traction control system, a brake pedal position sensor recalibration might be necessary.
Please note: Specific procedures can vary. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What does the BCM actually do on my 2000 Silverado?
The Body Control Module (BCM) acts as the central computer for your truck’s non-engine related electronics. It controls functions like power windows, door locks, interior and exterior lighting, the alarm system, wipers, and instrument panel warnings.
Do I need to take this part to a dealer for programming?
No. We handle all the programming for you before we ship the part. Simply provide us with your vehicle’s VIN during checkout, and the module will arrive ready to be installed, saving you time and money.
Where is the BCM located on my truck?
On most 2000-2001 GM trucks and SUVs like the Silverado, Sierra, and Tahoe, the BCM is located under the dashboard on the driver’s side, often near the steering column.
What if my airbag light is on after I install the new BCM?
This is a known possibility. It means the new BCM needs to be electronically ‘introduced’ to the airbag’s computer (SDM). A mechanic with a professional-grade scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules and turn off the light.
Is this part compatible with service number 9385236?
Yes, this BCM is a fully compatible replacement for service numbers 19208539, 9371990, and 9385236, covering a wide range of GM vehicles from that era.
